Firearm lock

ABSTRACT

A locking mechanism for placement into the ejection port of a gun. The device when placed into the port of the gun is keyoperated to prevent the removal of the device and will not allow the gun to be fired until it is removed therefrom. The device is also of such structure so that it cannot be forced out of the port. The core of the mechanism is also removable by the owner in order to provide quick key changes.

It is therefore the primary purpose of this invention to provide afirearm lock which will be adjustable so as to fit the ejection ports ofshoulder arms of various gauge sizes.

Another object of this invention is to provide a locking device whichwill have a slide bolt which will be adjustable in length, and when usedin combination with a slideable body portion of the device will make thefirearm lock adaptable to any size ejection port of a shoulder arm.

A further object of this invention is to provide a firearm lock whichwill have a wire loop lanyard, the lanyard providing a means of securingthe firearm lock on any convenient rod or the like.

Other objects of the present invention are to provide a firearm lockwhich is simple in design, inexpensive to manufacture, rugged inconstruction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of thefollowing specificationand the accompanying drawing wherein:

FIG. 1 is a plan view of the present invention shown installed withinthe ejector port of a shoulder firearm which is shown in phantom lines;

FIG. 2 is an enlarged plan view of the invention shown removed from FIG.1;

FIG. 3 is a side view of FIG. 2 shown in elevation with the extendedportion of the bolt shown in phantom lines;

FIG. 4 is a left end view of FIG. 3;

FIG. 5 is a right end view of FIG. 3; and

FIG. 6 is a bottom plan view of FIG. 3 which is shown partly brokenaway.

According to this invention, a firearm lock 10 is shown to include aplate 11 which is spot welded to tabs 11 of a member which hereinafterwill be described.

It shall be noted that an outwardly extending tongue 13 of lock 10serves to engage the forward interior of the ejection port of theshoulder firearm.

A gasket 12 is provided with an opening 14 in which the hollow main body15 is carried. An opening 16 through plate 11, receives the lockcylinder 17 and the bolt 18 of lock cylinder 17 includes a size spacer19 which is adjustable by means of screw 20. The adjustability isachieved by the varied thicknesses of spacer 19 which is secured byscrew 20. The tabs 11 of the main body 15 are spotwelded to plate 11 ofdevice 10.

Cylinder 17 is secured within the hollow main body 15 by means of a setscrew 21. A slideable internal member 22 is provided with an elongatedslot 23 which carries a serrated screw 24, screw 24 being threaded intoone side of the main body 15.

It shall be further noted that the slideable member 22 includes thetongue 13 and allows lock 10 to be adaptable to ports of various sizesthereby increasing the versatility of firearm lock 10. Once the properlength is determined, the screw 24 is then tightened.

It shall also be noted that the principal purpose of firearm lock 10 isto provide a means of locking the ejector port of a shoulder firearm anda loop lanyard 25 may be secured in a suitable manner (not shown) to theface plate 11 to allow firearm lock 10 to be secured on a rod or thelike, if desired.

It shall even further be noted that the use of lanyard 25 is optionaland the high sidewalls of elements 15 and 22 will always be at thebottom of the ejector port opening in order to prevent entry to theoperating parts of firearm lock 10 from the bottom of the shoulderfirearm.
